LAST FOR BOOTS AND SHOES.

Application filed August 6, 1923. Serial No. 656,052.

To all whom it may concern:

Be it known that I, PATRICE J ULIEN CAs- ENAVE, a citizen of France, and a resident of Salies-de-Bearn, Basses-Pyrenees, France, have invented a Last for Boots and Shoes,

which is fully set forth in the following specification.

In the U. S. Patent No. 1,165,950 filed January 28th, 1914, it has ben specified that it was possible to adjoin to a hollow last of the same kind as the one which forms the object of the prior French Patent No. 454,741 of February 24:, 1913, a solid last which is introduced into the hollow one, the latter being preferably open at its rear part so as to facilitate this introduction as a result of its elasticity.

The combination of this solid last with the hollow one allows to proceed to the lasting and then to the mounting or putting together of the upper leather either by means of tacks or nails, or by hand, without any difficulty in the same manner as on an ordinary last, and then to perform the sewing or nailing of the upper leather to the sole, after having rmoved the solid last, but leaving the hollow one.

However, as the applicant has been able to ascertain during the set of trials he has made, it is very difficult to remove the solid last because the same is made in one part and also because the hollow last, which'is open at its rear part, has a certain elasticity and is pressed with power against the said solid last in virtue of the pull exerted through the tongs or nippers action upon the upper leather.

It is with the purpose of obviating these difficulties that the applicant has devised the system of hollow and of solid last which forms the object of the present invention, these lasts being established so as to be able to resist the pull of the tongs and the blows resulting from the driving of the nails, this resistance exerting itself in every direction without any clamping of the hollow last against the solid one and in a more general manner without any displacement of the two lasts the one with reference to the other during the different operations.

To this purpose, according to the presentinvention, the solid last is made of several parts which are hinged together or can be separated the one from the other, which allows of taking the same to pieces, so asv to release the same and allow it to be removed from the hollow last. I

Furthermore, the hollow last, instead of being open 'at its rear part, is not out off in any way along its periphery, so as not to present any elasticity; however the heel portion of the hollow last can be connected by means of hinges so asrto facilitate the removal of the last without in any way distorting the upper leather.

The accompanying drawing given by way of example will allow one to easily understand the way in which the invention is car- 'ried out.

Figure 1 is a whole view showing the solid last in position on the hollow one, the latter being shewn in vertical section.

Figure 2 shows the solid last in vertical section.

Figure 3 is an external view of the solid last comprising three parts, that is to say a removable upper part or cap and two'other parts which are connected together through hinges.

Figure 4 is plan of the parts connected together by means of hinges.

Figure 5 is a perspective view of the hollow last.

' Figure 6 shows a modified form of the hollow last' provided with hinges.

Figures 7 and 8 show diagrammatically the operations of tacking the upper leather and of sewing or stitching the sole, these figures being sections made according to line xw of Figure 1.

Figures 9 and 10 are modified forms of sewing.

' In order to mount the upper leather, the solid last is first introduced into the hollow last d, this solid last being constituted by three parts, a, b, 0.

As shown in Figures 2 and 3, the connection of the several parts of the solid last can be obtained as follows:

A removable cap or cover a, of the same kind as those which form parts of the last-s as used by shoemakers, engages the part b in the usual manner, that is to say through introduction of the nipple 6 into the recess hollow last d, as shown in Fig. 1.

To the part b is mounted by hinges, at 6 the third member 0.

Moreover, the member a carries an ironband a whose end at is bent at right angle so as to bear against the edge 0 of the part 0, when the solid last is in the position in which it is to be introduced into the hollow last cl.

With reference to the hollow last (Z, the same can be made of moulded or pressed metal, aluminium for example, and does not show any break in continuity over the whole of its periphery, so that it is rigid.

In virtue of its construction in several parts, the solid last can easily be engaged into the hollow one through the top.

To this purpose, the parts Z), c, are first introduced into the position they occupy in Fig. 8, that is to say that they form between them a certain angle thereby diminishing the space between the point or tip of the part Z) and the heel portion of the part 0 according to the amount which is required to allow the whole of the two parts Z), 0 to be vertically engaged from the top to the bottom into the hollow last.

A pressure is then exerted upon the upper face Z) of the part Z), which has the effect of bringing the latter into the position of Figure 1 and it is then only necessary to put in position the. upper part or cap a.

It must be understood that it would be possible to cause the solid last to enter, with its members a, b, 0 in contact, into the hollow one from underneath, that is to say in covering the said solid last with the hollow one.

When the solid last is put in position in the hollow last (i, and that the whole is turned over into the inverted position, the cheek c of the part 0 of the solid last bears against the support (Z of the hollow last (Z, this bearing as well as the one resulting from the tip of the hollow last being neces sary to resist to the driving of the nails or tacks or to the stresses of the tongs or nippers.

Such being the case, the operations take place as follows, supposing the case of a putting together through nails or tacks followed by the sewing or stitching of the sole.

The solid last a, Z), 0 being placed in position in the hollow last and the upper leather being lasted, the tongs fold down the edges of the upper leather upon the first one f and the nailing or driving of the tacks 9 takes place in the usual manner.

The provisional fastening of the sole is also effected in any suitable manner, then the solid last is taken to pieces and removed from the hollow last 01. This taking down to pieces is effected in a very simple manner through removing first the cap a, then in inserting a hook into the hole Z) provided in the intermediary part b and in exerting a vertical pull so as to cause the hinge or articulation b to operate, which diminishes the interval between the front end or tip of the part b and the rear part of the part acting as a heel 0.

Under these conditions, it is very easy to remove the whole of the two parts Z), 0, from the hollow last. The hollow last is left in position in the shoe and then it is proceeded to the final stitching of the sole h. The latter can be in any suitable material, such as india-rubber, leather, or the like.

The sewing or stitching can be eifected either in the manner shewn in Fig. 8 on the edge of the sole, under the sole as represented in Fig. 9, or still in the angle as shewn in Fig. 10.

It will be understood that alterations can be made in the forms which have just been described; thus for example the solid last can be formed of any number of parts or elements which are either independent or connected together by means of hinges.

Moreover, the hollow last, instead of being formed of a single piece, can be formed of two pieces, as shewn in Fig. 6, d", d, hinged together at the joint being such as to form an abutment in the direction opposite to the one in which the removal of the hollow last is effected.

The process which has just been described including the use of a solid last made in several parts allows maintaining the lastinside the shoe during the manufacture of same up to the complete finishing.

It follows, particularly in the case of canvas shoes, tennis shoes, sandals, slippers and the like, that the gummed canvas, counters, stiffeners, dry on the last itself; the sewing 01' stitching, the polishing, and the like, also assist in maintaining the swelling and the general outlook of the shoe which it has been desired to obtain when the shape itself of the shoe has been devised or conceived.

When taking into consideration that the steaming and the passage through the drying-stove have been for some articles, such as the uppers made of felt or canvas, and the like, devised with the purpose of giving back to the shoe the swelling or contour from which it has been deprived through handling in the manufacturing process, it can be concluded that supposing that this steaming is necessary the same will take place upon the hollow last in question whence a saving in the work of reshaping or relasting which means a delicate operation, whereas it is practically impossible to relast or reintroduce the same last after stitching without spoiling and soiling the shoe.

The invention refers to all sorts of soles generally, whatever the nature of these soles may be.
